我有一个组件,其中[(ngModel)] = attrProps._value在用户输入上进行设置,并且在默认情况下已经存在时也获得值。 现在,有一个按钮可以在用户希望具有自定义值时指向值选项切换按钮。
但是,当用户单击刷新按钮时,输入字段中的值应该清楚吗?
@Component({
selector: 'n-customValue',
template: `
<mat-form-field class="inputfield-attr-view">
<input matInput [(ngModel)]="attrProps._value" placeholder="{{bKeeperService.getAttributeType(attrProps).displayAs}}">
<mat-icon matSuffix (click)="revertIcon()" class="editButton">
<img class="attributeview-button" src="../../assets/icons/refresh.svg">
</mat-icon>
</mat-form-field>
`
})
export class customValueComponent implements OnInit {
@Output() clickEvent: EventEmitter<string> = new EventEmitter<string>();
constructor(public myservice: customService) { }
ngOnInit(): void { }
revertIcon() {
this.clickEvent.emit('REVERT_EVENT');
}
}
我尝试使用元素ref,但无法解决。
@Component({
selector: 'n-customvalue',
template: `
<mat-form-field class="inputfield-attr-view">
<input matInput [(ngModel)]="attrProps._value" #searchInput placeholder="{{bKeeperService.getAttributeType(attrProps).displayAs}}">
<mat-icon matSuffix (click)="revertIcon()" class="editButton">
<img class="attributeview-button" src="../../assets/icons/refresh.svg">
</mat-icon>
</mat-form-field>
`
})
export class customvalueComponent implements OnInit {
@Output() clickEvent: EventEmitter<string> = new EventEmitter<string>();
@Input('nAttrProps') nAttrProps;
@ViewChild('searchInput') searchInput: ElementRef;
attrPropsValue;
constructor(public myservice: customService) { }
ngOnInit(): void { }
revertIcon() {
this.clickEvent.emit('REVERT_EVENT');
this.searchInput.nativeElement.value = '';
}
}
